Gas PRODUCER.

Application filed April 14, 1911, Serial N-c. 181,972. Renewed Jane 29,1928.

embodying my invention; Fig. 2 is a sec tion on line II-'II of Fig. 1;Fig. 3 is a detail of the valve opening and closing mechanism; Fig. 4 isa vertical section showmg a modified form of my invention and Fig. 5 isan end elevation thereof, partly in section; Fig. 6 shows in section a'modifica tion of the rate shown in Figs. 4 and 5; and Fig. 7 1s aperspective of one'ofj the sections thereof. i

My invention relates to producers which are capable of use in gasityingmaterials,

and iscomprised of apparatus and the method of using the, same, which Ishall hereinafter describe and. claim.

rial and the gas passes out and into the ofi'-' take 6. At the bottom ofthe "-ofltake 6 is -a waterseal 7, into which ash settles while the gaspasses off thrdugh the pipe 8. The central portion 9 of ritecylinder ispreferably of greater diameter than are the end portions, and is joinedto the end portions by the inclined walls 10 and 10.

In the central portion there is a door 11 of considerable size, so as toafford access to the interior of the cylinder and enable the removal ofclinkers which sometimes form therein, and also to permit any necessarrepairs to be made. V

it the feed-end of the-cylinder I have shown a chamber 12 for air orother oxygen hearing agent, having a central aperture 12, whichregisters with the end of the air supply pipe 13, and the air chamber inturn supplies air through piping 13 to a plurality of nozzles of tuyeres14, which are preferably positioned in apertures 15 in the inclined wall10'of the vessel, near the periphery of the central portion 9. Connectedwith each tuyere 14 is a valve 16, which it opposite sides of the lineof travel of, the

valve. As the cylinder revolves the arm 20 of each valve strikes the pin18 which rotates the valve to open position, thus admitting the elasticfluid into-the vessel below the fuel level. Further rotation of thecylinder will bring the other arm 21 otthe valve handle into contactwith the pin 19, which rotates the valve to close it. As is indicated inFigs. 2 and 3, the pins 18 and 19 are positioned in-apertures 22 iiistrap 17, so that the length of time during. which the elastic fluid isso plied for combustion may be varied as diasired.

To permit expansion and contraction, and also to prevent the escape ofgas between the fixed and movable arts, I have ro'vided an expansionjoint 24 tween the ischarge aperture 5 .and the olftake 6.

In the production of, producer gas in the apparatus just described,combustion is started in the interior 6f the producer, the

necessary fuel preferably being inserted through the door 11. When theinterior oh the producer has become, hot enough, fuel is fed through thescrew conveyor 4 into t ,e

vessel, and the vessel is set in rotation. '1 e areas or zones of.greatest combustion-*" 'f gasification are those immediately aroungieach tuyere 14, and, as. the vessel rotates, the fuel immediately infront' ofit rolls over and constantly shifts, so that the fuel which isbrought, into these zones of greatest combustion or gasification shiftsand changes, so as to constantly bring new fuel into each of the zonesof intense combustion or gasification. With light fuels, such asanthracite slush, buckwheat, sawdust, lignite, bituminous slack, and thelike, the material is frequently'so light that it blows away (romimmediately in front of each ori inal mass.

tu'yere, so that a certain rate of travel is the grate sections 27 whenthey are beneath necessary with'such material in order to keep the fuelbed. the fuel massed about each successive tuyere, In Figs. 6 and 7, Ihave shown a modinnd in the zone of intense/ combustion theretication ofthe grate sections 27 which are about. In this way the porosity of, themass illustrated in Figs. 4 and 5. This modificais kept uniform, and theformation of chimtlon consists in forming the sections of L- neys blowholes, etc., which permit the s aped castings 27, having their. forwardununiform escape of gas through the mass, ends 33 closed and their rearends provided is thereby obviated. This results in obtain h penings 29'therein.
